MACHINERY OF MILLS FOR THE MANUFACTURE OF GRAIN INTO FLOUR R MEAL.

Specification forming part of Letters Patent No. 396, dated January 9, 1830; Reissued September To all whom it may concern Be it known that I, JESSE C. SMITH, of the town of VVhe'eling, county of Ohio, and State of Virgina, have invented, constructed, made, and applied to use certain new and useful Improvements in Machinery of Mills for the Manufacture of Grain into Flour or Meal, which saidimprovements are herein specified and particularly set 10 forth. A, A, A, A, represent a sidevlew of the cast iron husk, or frame; B, B, the nuts by which the frames are held together; C, the bridgetree; D, the box in which the foot of the spindle rests; E, the spindle; F the curve upon which the band rests; G, the

position of the bed-stone within the frame; H, H, the top-stone or runner; I, the drum, resting on the spindle; J, the balance-rim;

K, the pressure-rod; L, the screw connecting the pressure-rod with the top-frame; M, M, top-frame upon which the hopper rests; O, O, the gudgeons of the top-frame M, to accommodate the motion of the frame when necessary; P, a rod of iron connecting the top-frame with the bridgetree C; Q, the regulating screw by which the running stone is elevated or depressed at pleasure and the nut on which is placed in the bridgetree; R, the screw bearing upon the top of the regulating screw.

What I claim as new and as my invention'is V 1.-The connecting what is above called the top-frame or whatever substitute may be used to resist the upward pressure-rod K, with the bridgetree by a piece of timber (as is shown in the drawings Nos. 2 and 3, P,) or otherwise thereby producing the effect that when the regulating screw Q, elevates or depresses the bridgetree (and consequently the spindle-running stone and pressure-rod) that the relative position of the faces of the stones is secured against any change by reason of an increased or diminished velocity of the runner.

2. The mode or manner of depressing as I [Fmsr PRINTE 1914.]
